Norway Application July 17, 1939, Serial No. 284,946.

- p In Norway January 25, 1939 6 claims.' (ci. 2go-11.35) l ofcourse, beestablished in different ways. This n The present invention relates tofastening means for the'shoe on sporting appliances, such as skis,skates or the like and is of that type where the fastening meansconsists in longitudinally divided foot plates with substantiallynormally extending side guides for the front end ofthe sole of the shoeand where means are provided for adjusting these two parts of thefastening means sideways in order to adapt the same for shoesofdifferentV sizes.

In the usual construction of such fastening means as they commonly areseen in combination with skis, it is necessary when mounting the same onthe skis, to take proper care that the shoes which are to be used inconnection with the fastening means will t into the same; and as thedimensions of the shoes when a person purchases new ones, and also thedimensions o-f the shoes if different persons are to use the samesporting appliances, differ, it is of great importance to provide easilyaccessible and easily handled adjusting means for varying the transversedistance between the side members of the supporting means.

Several different types of such adjusting means have been proposed. Noneof these has, however, fullled all the requirements which are necessaryfor producing such articles on a commercial scale and at the same timefor producing an article which will fulfill all requirements.

According to the present invention the fastening means for sportingappliances as above described are provided with adjusting means which atany time can be used for adjustments in transverse direction by means ofa simple hand movement.

One object of this invention is thus to provide fastening means for theshoe on sporting appliances, where these fastening' means comprise twoha1ves,-each generally formed in an angle,A

two halves of the fastening means, when the adjusting means is operated.

A permanent attachment of the fastening means to the top of the sportingappliances may,

may be done directly by'means of screws arranged to pass throughsuitable slots in the said. foot plates, or it may be arranged to actthrough the means of a coverplate .which again is provided i with holes,adapted to receive screws which can be used for pressing the said coverplate in frictional engagement against the said foot plate.

The fastening means according to this inven` tion may, of course,be'given different embodiments, and some preferred embodiments for theinvention will be described in the appended description with referenceto the drawings. In this description several details of novel characterand Fig. 5 is a View `from above of the two foot` pplates. I

Fig. 10 is a section through the adjusting means at the line X-X in Fig.6.

In the above figures, corresponding reference numerals refer tocorresponding parts.

When considering the embodiment shown in Fig. 1, this consists infastening means I and 2 `with foot plates 3 and 4 and side guides 5 and6. The foot plates 3 and 4 have two substantially oval-shaped aperturesl, 8 (see Fig. 5) through which the screws-to'provide for permanentattachment may pass freely. On top of the foot plate there is arranged acover plate 9 with a central aperture I0 (see Fig. 7) and with bevelledscrew holes II, I2, I3, I4. Below the foot plate there is arranged anadjustment member VI5 shaped as a disk, comprising spirally formed slotsI6 and II, into which projections, fingers or the like I8 and Ill-whichmay be a component part of the material in the foot plates 3 and 4maypass.

In order to prevent that the two lfoot plates 3 2'A l j y and 4 and thecover plate 9 may move in relation to each other after the parts havebeen tightened down by the screws, there may be arranged corrugations 43and 44 at the front end of the foot plates. TheseV corrugations or teethmay be arrangedon curved surfaces and may be inclined downwards andforwards. Corresponding `corrugations or teeth may be arranged on thecover plate 9 at 45 in such a way that when the cover plate is tighteneddown against the foot plates, the two corrugatedinclined surfaces iwillmesh and tend to pull the coverplate in the inwards direction. As amodified embodiment such corrugations may be arranged on the sides ofthe cover plate.

At the back edge of the foot plates 3 and 4 there are also arrangedgroups of teeth 46 and 41 inclined forwardly in the foot plate, and inthe cover plate there are arranged teeth 48 and 49 which are intended toco-operate with the said teeth 46 and 41 on the foot plates, when thecover plate is tightened down. The fastening means are provided withflanges 23, 24, adapted to en` gage with the top side of the sole of theshoe.

When the above mentioned parts have been primarily mounted on top ofeach other von the ski and primarily attached thereto by1oosely`arranging the screws through the holes II and I2,

`I3 and I4, one may by means' of a screw driver engage the slot 25 inthe adjusting member I5 and provide for a turning of the same about anaxis which is substantially normal to the plane of the foot plates. Theco-operation between the notches I8 and I9 and the slots I6 and I1 inthe adjusting member will by this turning provide for'the movement ofthe two halves of the fastening means transversely and in oppositedirections.

By such adjustment one may easily iind the desired dimension and anglebetween the two side guides 5 and 6, and when this dimension has.

been found to Acorrespond to the dimension of the shoe which is tobeused with the fastening means,.the screws in the holes II, I2, I3 andI4 may be tightened, whereby all the parts will be locked in position.

In the embodiment of the invention which v is shown in the drawings, theadjusting kmember l5 has been madeup of several parts inv order toinsure that the adjusting member under all circumstances shall ada-ptitself as well as possible for the purpose.l I i The adjusting member I5is here constructed of separate circular plates 36 and 31, see Figures4, 6 and 10. The plate 36 is attached to a hollow shaftlike member 38which has a groove 25, adapted to receive theworking edge of the screwdriver for the purpose of adjustment. The plate 31 is movably carried onthe shaft 38 and is prevented from falling off the shaft 38 by means ofa shoulder 39 on the shaft. The plate 31 may thus move in the directiontowards or away from the plate St within a certain distance. A springplate 4I! is arranged between these two plates in such a way that undernormal circumstances the plater31 will tend to adopt a position as faras possible away from the plate 35 and in such a way that the plate 36,when'y the cover plate 9 is tightened down, will be forced up into thecircular aperture IIl in thisy plate, while the plate 31, which isprovided with spirally formed slots will be forced down against the,foot plates 3 and 4 and thus insure the engage- Thedifferent holes II,I2, I3 and I4 in the cover'plate 9 are further shapedin such -a way thatthe side edges of these holes are bent down and formconicallyshapedguidng members onv the under side `of the plate, which'clearly canbe seen from the Figures 2, 3 and 8j The plate 31 is` now dimensioned insuch a way in relation to the locationof these holes.; that it will bevy guided at its circumference at .four points by coming into contactwith these depressions. One f may further, if this is found advisable,arrange notches 4 Land `42 in the cover plate at such loca;v

tent and commonly well known rmeans for this purpose may berused; asthis means further is no part of this invention, no description has beengiven of such means. 1' l I claim: f
